Companies reporting:

Aphria Inc. — The marijuana producer says CEO Vic Neufeld and co-founder Cole Cacciavillani will be leaving their executive roles at the company, but will remain on the board. Neufeld says he and Cacciavillani will begin the transition process immediately, and at the appropriate time, they will both step down from executive positions at Aphria. The change comes as Aphria faces allegations by short-sellers questioning the company's acquisitions in Colombia, Argentina and Jamaica. Aphria has denied the allegations, but established a special committee of independent directors to review the deals.

Corus Entertainment Inc. (TSX:CJR.B). Up 31 cents, or 5.78 per cent to $5.67. Corus's earnings came in below estimates as its first-quarter profit fell from a year ago due to an accounting change related to its TV brand assets, but revenue edged higher due to gains in television advertising. The television, radio and production company says its profit attributable to shareholders fell to $60.4 million or 28 cents per diluted share for the quarter ended Nov. 30 as amortization charges rose due to the accounting change. The result compared with a profit of $77.7 million or 38 cents per diluted share a year ago.

Cogeco Inc. (TSX:CGO). Up $4.64 or 7.6 per cent to $65.42. Cogeco says an acquisition by its cable and internet segment pushed up first-quarter revenue, but profit was down due to higher costs associated with integrating and restructuring the business. The Montreal-based company says last year's acquisition of the MetroCast cable systems by Cogeco Communications Inc. was the main reason Cogeco Inc.'s revenue increased to $674 million from $585.7 million last year. But Cogeco Inc.'s net income attributable to owners of the corporation for the quarter ended Nov. 30 fell to $26.2 million or $1.60 per diluted share.
